Arterial Strike All units in the formation must be held in Strategic Reserve embarked in Raider or Venom Transports. They may enter play in any of the owning player's turns. To represent the element of surprise, in the Shooting phase of the turn they enter play, all units in this formation may re-roll failed To Hit rolls.
Arterial Webway Portal When deploying fortifications at the start of the battle, you must set up an Arterial Webway Portal. The Arterial Webway Portal uses the large blast marker and can be used by vehicles. It may be placed anywhere on the table outside of the opposing side's deployment zone.
Any of your units arriving from reserve may move onto the board from the portal marker's edge instead of entering as normal (it does not matter whether these units were intending to Deep Strike, Outflank, simply move on from their own table edge, and so on). The portal counts as impassable terrain and cannot be destroyed.
